We have developed a fire sensor that we'd like to enable to send alerts using Alexa. For example if we detect smoke in the kitchen, we'd like every Alexa in the house to announce 'Warning, smoke detected in kitchen'.
The ring doorbell can now do effectively the same thing - if I enable it, if the doorbell is pressed all the Alexa's will make an unsolicited announcement 'someone is at the front door' without me asking for my notifications.
Is this feature also open to third party applications? ChangeReports appear to allow me to notify Alexa if a state changes (e.g. fire alarm is true) but it's not clear to me from the documentation whether that can trigger an unsolicited announcement from Alexa. Asking 'Alexa, is there smoke in the kitchen?' is less useful.
